LAMP-CHIMNEY HOLDER.

SPECIFICATION forming part Of Letters Patent N 0. 618,513, dated January31, 1899.

Application filed July 9,1898. Serial No. 685,508. (No model.)

To aZZ whom it may concern:

Be it known that I, ABNER PERCY LooKE'rT, a citizen of the UnitedStates, residing at Knoxville, in the county of Knox and State ofTennessee, have invented certain new and useful Im pro vements'inLamp-Chimney Holders, of which the following is a specification.

My invention relates to chimney-holders, and has for its object toprovide means whereby a lamp-chimney may be securely held on the burnerbeyond the possibility of accidental displacement and yet be capable ofbeing readily removed therefrom.

To this end myinvention consists of a lampburner having anupwardly-turned and inwardly-projecting segmental flange on the base ofthe burner engaging a suitablyforlned lug or shoulder on the chimney.

The invention further consists in an upwardly-turned inwardly-projectingsegmental flange on the base of the burner engaging a suitable lug orshoulder on the chimney, combined with means retaining the chimney inplace when the lug or shoulder is engaged by the flange.

. The invention further consists in a lampchimney having segmental lugsprojecting outwardly from the base thereof.

Preferably the means for retaining the lugs of the chimney in positionunder the flange of the burner consist of a rigid projection preventingthe chimney from turning in one direction and a spring catch securing itagainst turning in the opposite direction; but I may, if founddesirable, form the firstmentioned projection also in the shape of aspring-catch.

I have illustrated one form which my invention may assume in theaccompanying drawings, in which Figure 1 is a side elevation of alampburner with my improved holder. Fig. 2 is a plan of Fig. 1. Fig. 3is a central vertical section of Fig. 2, showing a chimney in place onthe burner. Fig. 4 is a horizontal section on theline 4 4, Fig. 3; andFig. 5 is a perspective View of the base of a chimney, showing the lugsthereon.

Like letters designate like parts in all the views.

A is a burner of any preferred construction, and B is a segmental flangeprojecting upward from the outer periphery of the base and provided withan inwardly-turned lip b. Preferably the flange B is made integral withthe base of the burner; but it may be formed separately and soldered orotherwise secured to the base. There may be one or more flanges Bsecured on the burner. In the present instance I have shown twooppositelydisposed flanges each extending for a distance a little lessthan one'quarter of the circumference of the burner-base.

O is a chimney of any desired form, having a suitable lug or lugs o, thenumber of lugs on the chimney preferably corresponding with the numberof flanges on the burnerbase. By placing the chimney on the burner sothat the lugs c occupy the spaces between the flanges B and then turningthe chimney the lugs thereon will pass under and be engaged by the lipsZ) on the flanges. For the purpose of preventing the chimney from beingturned too far the flange is provided with a stop 1), Figs. 1 and 4, anda spring-catch 1)", Figs. 1 and 2, is arranged to engage the shoulder onthe lug in opposition to the stop b and prevent backward rotation of thechimney. This spring-catch may be formed on the flange'B, as shown at bin Figs. 1, 2, and 3, or it may, if preferred, be formed on the base andproject upward through a slot or opening, as shown at N, Fig. 4. It isevident that the shoulder or stop I) may be rigid, as shown in Figs. 1and 4, or may be in the form of a springcatch without departing from theprinciple of my invention. Furthermore, it will be understood that thespringcatch 1)" and the stop-shoulder Z) may be formed on the sameupwardly projecting flange or otherwise, the essential feature beingthat a stop-shoulder shall be provided to prevent the turning of thechimney in one direction and a suitable catch to engage and hold it frommovement in the other direction, the stop and catch acting in oppositionto each other.

My invention is equally applicable to lamp= burners, gas-fixtures, andsupports for electric-light globes and the like, and it is to beunderstood that where the expression lamp= burner is used herein it isto be regarded as the equivalent of the supports employed in similarrelations on gas and electric-light fixtures.

Having thus described my invention, I

'claim 1. The combination with a lamp-chimney having anoutwardly-projectinglug thereon, of alarm p-burner having aninwardly-projecting segmental flange on the periphery thereof, a stop orshoulder on the burner in the path of the lug on the chimney anddetermining its position on the burner, and a spring-catch acting inopposition to the stop and preventing backward rotation of the chimney,substantially as described.

2. A burner having an upwardly-projecting inturned flange secured to itsbase, a stopshoulder thereon, and a retaining-catch oppositely disposedto said stop-shoulder, substantially as described.

In witness whereof I have hereunto set my hand and seal this 26. day ofJuly, 1898.
